Use 1
Flavoring agent. The general dosage is 0.2% ~ 0.5%. In addition to using alone, it should be combined with nucleic acid seasonings such as ribonucleotide and sodium inosine to form compound seasonings to improve the effect.
Use 2
Sodium glutamate is the most widely used savoury agent at home and abroad, co-existing with salt can enhance its taste effect, and 5' -inosine sodium or 5' -guanylate sodium used together, more have the effect of multiplication. China's provisions can be used in various types of food according to production needs.

Glutamic acid is widely found in plants and animals and is a natural nutrient in food. After consumption, 96% of glutamate is absorbed in the body, and the rest is oxidized and excreted in the urine. Although glutamic acid is not an essential amino acid, it can synthesize other amino acids by amino transfer with ketoacids in nitrogen metabolism. Glutamate has the effect of reducing toxins in the blood. When liver function is impaired, the amount of ammonia in the blood increases, causing serious nitrogen metabolism disorders, leading to liver coma, and glutamate can act with ammonia to reduce the amount of ammonia in the blood. In addition, brain tissue can only oxidize glutamic acid, but not other amino acids. Glutamine acts as an energy source for brain tissue when glucose is in short supply, so glutamate is necessary to improve and maintain brain function. Sodium glutamate has a strong meat flavor, MSG diluted with water to 3000 times can still feel the flavor, widely used in the family, catering industry, food processing industry (soup, sausage, fish cake, spicy sauce, canned food, etc.). In addition to MSG, sodium aspartate, sodium inosine and sodium guanylate are commonly used as food flavor agents. The umami taste of sodium glutamate is 100, and the relative umami taste of the other three umami agents is: sodium aspartate 30 inosine sodium 4000 guanylate sodium 16000 inosine sodium, guanylate sodium and sodium glutamate are used at the same time, which has a synergistic effect and can improve the umami taste, also known as fresh agent or strong MSG. After a long time of heating, the aqueous solution of sodium glutamate will cause water loss and become sodium pyroglutamate. For example, pH6.9, 10% aqueous solution, heated at 100℃ for 4h, sodium pyroglutamate content is 2.1%; When heated at 115℃ for 4h, the content is 5.7%. Although sodium pyroglutamate is harmless to the body, it has no umami flavor, so it is generally reasonable to add it near or after the pot is cooked. The general concentration of MSG is about 0.2-0.5%. At present, China is one of the world's largest monosodium glutamate production and consumption countries, and Japan is the world's first monosodium glutamate consumption country. After decades of research and tests have proved that MSG is one of the important nutrients that the human body needs, is a natural substance that exists in human food and the human body itself, and the human body intake of MSG is completely digestible and absorbed, and carries out normal metabolism. Therefore, the 19th meeting of the Food and Agriculture Organization and the World Health Organization Regulatory Committee on Food Additives held in the Netherlands in 1987 decided to cancel the limit of MSG in food. In addition to the above pharmaceutical and seasoning uses, sodium glutamate can be used as an organic synthesis intermediate in industry, but in the world annual output of more than 200,000 t, the proportion of other uses is very small.
